usually they'll take it off the negotiated price, so it won't seem like they are hitting you any extra... it's just a PITA for them to track it down and get it there.

personally i'd start calling dealerships to find out which one has what you want or will be getting one shortly, get a quote from them and keep moving along getting quotes, one better than the next.

let the dealerships fight for you.

sean did this with his RSX a few years back... he went online, got a quote from a dealership like 250 miles away, and then went to like 5 or 6 along the way until he got to the one closest to him

he got the exact car he wanted for much less than MSRP and that was after TTL
